ABSTRACT
A novel aerobic, spore-forming, marine actinomycete, designated strain LHW63015T, was isolated from a Craniella marine sponge collected in the South China Sea. The strain formed extensively branched substrate and aerial mycelia which carried long and crooked spore chains composed of ridged spores and spherical pseudosporangia. Strain LHW63015T contained meso-diaminopimelic acid as the diagnostic diamino acid. Glucose, ribose, mannose, galactose and madurose occured in whole-cell hydrolysates. The predominant polar lipids were hydroxyl-phosphatidylethanolamine, phosphoglycolipid and ninhydrin-positive phosphoglycolipid. MK-10(H4) and MK-10(H6) were the predominant menaquinones. The major fatty acids were 10-methyl C17ââ0 and C17ââ1ω8c. The G+C content of the genomic DNA was 70.8 mol%. In phylogenetic analysis based on 16S rRNA gene sequences, strain LHW63015T fell within the family Streptosporangiaceae and formed a distinct monophyletic lineage adjacent to the genus Sphaerisporangium, and shared the highest 16S rRNA gene sequence similarity of 96.2â% with Sphaerisporangium album YIM 48782T. On the basis of the polyphasic evidence, a novel genus and species of the family Streptosporangiaceae, for which the name Spongiactinospora rosea gen. nov., sp. nov., is proposed, with the type strain LHW63015T (=DSM 106635T=CCTCC AA 2018019T).
